It appears the kingpin is vertical which is a great start in your CHS. No need to compensate for steering inclination, just build in some caster and get the kingpin in the middle of the wheel and start welding.
I wonder how many degrees of movement that spindle has. I recall that we get about 14 degrees in each direction of our C14/ZX14 CHS. Have you thought about adding a swaybar to your outfit?

degrees of movement? do you mean the amount of steering?
lock to lock was a bit limited, i am considering remaking the front end as i was not happy with the braking ability, wheel mounting was poor and when stationary steering was really heavy, and seeing what you guys are using has given me lots of ideas for inprovement,
